There are two very different things inside Overpower (King Louis XIII x Blue Power IX2). King Louis XIII: King Louis XIII, the indica-dominant OG also written King Louie. And Blue Power IX2: Blue Power after another decade of selection. The known parent is doing real work here - it is what turns an interesting pairing into a line that comes out the same way twice.
Written this way, King Louis XIII is the mother and Blue Power IX2 the pollen donor. Reversing a cross is not a formality; which plant carries the seed shapes what comes out of the pack.
Genetic Lineage
- Mother: King Louis XIII. King Louis XIII, the indica-dominant OG also written King Louie. Given as given as OG Kush crossed to LA Confidential. It takes the piney fuel backbone from OG Kush and the dense resinous structure from LA Confidential.
- Father: Blue Power IX2. Sin City's own Blue Power, taken further. Built from an inbred continuation of Blue Power. IX2 is not a new cross. It is Blue Power inbred and selected over more than a decade and then released feminized, and the point of that work is predictability - the flagship behaving the same way every time rather than throwing the range an F1 does. When Sin City put IX2 on a pack rather than plain Blue Power, they are saying the known half of the cross is now genuinely known.
- Why it is worth a pack rather than a look. The two sides are far enough apart that seedlings genuinely differ. That range is the product.
Flavor and Aroma Profile
The nose is where these two argue hardest.
- The Aroma. Musky pine and skunk with a thread of citrus - earthy, piney and woody from the King Louis XIII side, against the Blue Power nose - sweet kush and sour fuel over creamy blueberry from the Blue Power IX2 side.
- The Taste. Pine and fuel over a kush base, with LA Confidential's sweet spice behind it up front, turning to berry and lemon closing earthy, as the original does through the exhale.
The two halves, side by side
- Two noses, one pack. King Louis XIII contributes musky pine and skunk with a thread of citrus - earthy, piney and woody. Blue Power IX2 contributes the Blue Power nose - sweet kush and sour fuel over creamy blueberry. Which dominates is the main thing that varies.
- Build. On the King Louis XIII side: roughly seventy percent indica; dense small-to-medium buds, bright green with purple through them and orange pistils, under a heavy coat of trichomes. On the Blue Power IX2 side: it keeps Blue Power's indica build and its resin, with the variation pulled in by generations of selection. Select early rather than trying to train your way out of it.
- Opposite ends. King Louis XIII is reported as famously heavy and sedating - the LA Confidential side shows most here; Blue Power IX2 as physical relief without the mood going flat. The cross sits somewhere between and moves plant to plant.
Cultivation and Growth Traits
- Plant Structure. The two parents disagree here, so plan for range. King Louis XIII is roughly seventy percent indica; dense small-to-medium buds, bright green with purple through them and orange pistils, under a heavy coat of trichomes. Blue Power IX2 is it keeps Blue Power's indica build and its resin, with the variation pulled in by generations of selection.
- Before the flip. Decide the shape now. These lines do not tidy themselves up once they are running.
Effects and Experience
- The Mind. Growers describe King Louis XIII as famously heavy and sedating - the LA Confidential side shows most here.
- The Body. Blue Power IX2 is reported as physical relief without the mood going flat, and that is the side supplying the weight here.
